The waist of combination and pelvic support equipment 30 further comprises pelvic support equipment or has the assembly 122 of pelvic support member 126, and this pelvic support member 126 can operate to provide support to the pelvis area that is sitting in the people in seat 10.Pelvic support member 126 is designed to cosily and effectively reduce or eliminate the rotation backward that pelvis increases along with lumbar support.Mobile or maintenance pelvis ability forward can help pelvis and backbone to be repositioned onto preferred biomechanics geometric configuration.As further described below, pelvic support is applied in rumpbone/coccyx side, thereby avoids and prevented uncomfortable on rumpbone or coccyx, direct and the concentrated pressure in center.
Graphic pelvic support member 126 is positioned to the contiguous bottom of back of seat 14 and the rear portion of seat board 18 and has the first and second side support sections 130 that are connected by centre portion 134 (seeing Fig. 2).Side support section 130 separates the left side that the right side of longitudinal axis 58 and another side support section 130 separate longitudinal axis 58.Graphic pelvic support member 126 is formed by the bar of the shape of cross section with constant, makes the far-end of bar limit the end of the side support section 130 of the J-shaped of reversion.But other structure of pelvic support member 126 is also expected.For example, bar 126 can be the parts of injection molding, punching press or die casting, and it has the shape of cross-sectional plane constant or that change.In addition, side support section 130 can aspect shape and/or material, change to adjust the sensation of side support section 130 to pelvis (for example, harder or softer material, and contact more greatly, less and different region and position).The side support section of graphic J-shaped can change (for example seeing Figure 13 and Figure 14) or other shape forming V-shape or U-shaped.In addition, side support section 130 can take the form of oar (, cross-sectional plane is solid) of wide variety of shapes so that more mating surfacess region to be provided.
As best illustrating in Fig. 3, Fig. 4, Fig. 9 and Figure 10, side support section 130 be positioned at described 54 below and as the parts of pelvic support member 126 first, be movably between retracted position (seeing Fig. 3 and Fig. 9) and second, extended position (seeing Fig. 4 and Figure 10), its pelvis area to rumpbone/coccyx side of user provides support.It is the side (, spaced apart from it) that how to be arranged on longitudinal axis 58 spaced apart from rumpbone/coccyx to the direct support of pelvis area that Fig. 6 has schematically illustrated what set up at 136 places, region by side support section 130.This structure eliminated by heart be applied to the uncomfortable pressure of rumpbone/coccyx of user, and alternatively near pelvis ridge and around soft tissue, exert pressure.
With reference to figure 2a, Fig. 3, Fig. 4, Fig. 9, Fig. 9 a and Figure 10, the centre portion 134 of pelvic support member 126 comprises arcuate section 138 (only illustrating in Fig. 2 a, Fig. 3, Fig. 4, Fig. 9, Fig. 9 a and Figure 10), and described arcuate section 138 extends along the direction with backward downward with respect to back of seat 14 from side support section 1 30.As best illustrating in Fig. 9, Fig. 9 a and Figure 10, in the time observing from bottom, arcuate section 138 has recessed sweep.Arcuate section 138 is transformed between arcuate section 138 the roughly straight connecting bridge 142 laterally extending of the centre portion 134 that extends and (sees Fig. 2 and Fig. 2 a).
To the supporting construction for pelvic support member 126 be described about Fig. 2 a, Fig. 9, Fig. 9 a and Figure 10 now.Centre portion 134, and more specifically the connecting bridge 142 of pelvic support member 126 is supported by load-carrying element 146 movably, and this load-carrying element 146 is connected to the base portion 38 of framework 34 movably.Movably load-carrying element 146 comprises one or more bracket portions 150, and this bracket portion receives and support and connection part pivotally 142.A pair of guiding elements 154 connects with base portion 38 and is further supported by the part extending laterally that receives bar member 44 separately.Each guiding elements 154 comprises the bracket portion 158 that receives bar member 44.Therefore, guiding elements 154 is roughly static with respect to seat 10.Guiding elements 154 comprises arc guiding surface 162, this arc guiding surface roughly in curvature corresponding to the curvature of the arcuate section 138 of pelvic support member 126.In other words, the sweep raising up of arc guiding surface 162 receives the recessed lower surface of arcuate section 138 and roughly conforms to it.Guiding elements 154 along the direction of the user in being sitting in seat 10 be positioned at arcuate section 138 before.Arcuate section 138 also by the arc guiding surface 166 forming in the base portion 38 of framework 34 (seeing that Fig. 2 a and 9a-only illustrate) the supporting on rear side of arcuate section 138, so that arcuate section 138 is clipped between base portion 38 and guiding elements 154 slidably.
The motion of pelvic support member 126 between retracted position (seeing Fig. 9) and extended position (seeing Figure 10) controlled by actuator 180, and described actuator 180 is installed to the body part 38 of framework 34 and can be operated to control by user the position of lumbar support member 54 and pelvic support member 126.In Fig. 1-10 in illustrated embodiment, single actuator 180 is synchronously controlled both motions of lumbar support member 54 and pelvic support member 126, so that lumbar support member 54 moves and can not independent operation together with pelvic support member 126.
As best illustrating in Fig. 5 a, actuator cable 184 extends from actuator 180, continuity in the passage 188 forming in the lower surface of load-carrying element 146 movably, and stop at termination member 192 places that are being fixed to base portion 38.In illustrated embodiment, termination member 192 is taked the form of barrel-shaped terminator, but other stops arranging and can substitute.The actuating of actuator 180 is retracted in actuator 180 cable 184, thereby has shortened the length of cable 184, and it causes that again movably load-carrying element 146 is with respect to the motion upwards (seeing Fig. 9 and Figure 10) of base portion 38.Because movably load-carrying element 146 supports the connecting bridge 142 of pelvis load-carrying element 126, so movably the motion upwards of load-carrying element 146 has also caused the motion upwards of pelvic support member 126.The motion upwards of pelvic support member 126 is guided by the arc guiding surface 162 of guiding elements 154 and the arc guiding surface 166 of base portion 38, they clip the arcuate section 138 of pelvic support member 126 slidably, with set up along bow-shaped route from Fig. 3 and the position shown in Fig. 9 to the pelvic support member 126 of the position shown in Fig. 4 and Figure 10 upwards and the moving of arching upward forward.For the people who is seated, this bow-shaped route of motion, and cause be applied to the natural rotation path of hyperpelvic power corresponding to pelvis.Along with waist support bracket 54 also provides additional support to user's lumbar region, side support section 130 extends to engage cosily provide support to user's pelvis area with the rear portion of waist support bracket 54 in the mode upwards and forward arching upward.
The a pair of biasing member of retracing spring 196 forms assists pelvic support member 126 to be moved back into retracted position from extended position.With reference to figure 2, Fig. 3, Fig. 4, Fig. 9 and Figure 10, a retracing spring 196 connects with the base portion 38 of each side support section 130 and framework 34.In illustrated embodiment, each retracing spring 196 is hooked at one end on side support section 130 and at other end place and is hooked on base portion 38 so that pelvic support member is biased into retracted position.Along with pelvic support member is moved to extended position by the actuating by actuator 180, the bias voltage of spring 196 is overcome, and causes spring 196 to stretch, as shown in Fig. 4 and Figure 10.Once the potential energy that actuated actuators 180 to elongate cable 184, is stored in spring 196 just helps pelvic support member 126 to be moved back into retracted position.Understand because because the weight pelvic support member 126 of the user in seat 10 can oneself be retracted, so spring 196 is optional.And for graphic retracing spring 196, it can be alternative that other retracing spring or bias voltage are arranged.
As mentioned above, actuator 180 is controlled both be synchronized with the movement of waist support bracket 54 and pelvic support member 126.The crust 106 that memory is connected to transverse member 48 is wrapped in actuator cable 110, and described actuator cable 110 can operate with mobile actuating and be with 86, and therefore between extended position and retracted position, wraps up described 54.As the best in Fig. 5 a illustrates, base portion 38 and cable 110 that the lower end of crust 106 is coupled to framework 34 extend around the lower surface 200 being formed by base portion 38 from the lower end of crust 106, and stop at clearing end 204 places, described clearing end 204 is fixed on movably load-carrying element 146.In illustrated embodiment, clearing end 204 is taked the form of received barrel-shaped terminator in groove 208, and described groove 208 forms in load-carrying element 146 movably, but, can use other to stop structure.Along with load-carrying element 146 is movably because cable 184 moves up by the retraction of actuator 180, clearing end 204 also moves up, thereby causing that cable 110 slides and pulls upper load-carrying element 78 downwards along the lower surface 200 of static base portion 38 activates and be with 86 and described 54 with bending.The length of setting up actuator cable 110 and 184 is to provide the motion of appropriate amount of the pelvis of combination and the various members of lumbar support device 30 to obtain being synchronized with the movement of expectation of waist support bracket 54 and pelvic support member 126.
Figure 11 and Figure 12 illustrate the pelvis of combination and the second embodiment of lumbar support device 230, are depicted as for clear and remove described 54.Equipment 230 in many aspects parts similar and same with equipment 30 has given same Reference numeral.A difference is that equipment 230 comprises that two actuators instead of an actuator are to provide the independently operability of waist support bracket 54 and pelvic support member 126.Actuator 234 can operate the position to regulate as described above pelvic support member 126 between extended position (seeing Figure 12) and retracted position (seeing Figure 11) with respect to the identical or similar mode of equipment 30 by user.Substitute clearing end 192 places of actuator cable 184 on base portion 38 are stopped, cable 184 can extend to the second actuator 238 and stop at the second actuator 238 places.
Actuator 238 can be operated to regulate by user the position of waist support bracket 54.Actuator 238 is arranged on equipment 230 and opposite side actuator 234 on base portion 38.Crust 242 and actuator cable 246 extend and connect in the identical mode about equipment 30 discussed above with transverse member 48 (and/or plate discussed below 250) and upper load-carrying element 78 from actuator 238.Can operate actuator 238 to retract and to stretch out actuator cable 246, with mobile upper load-carrying element 78, and therefore between extended position (seeing Figure 11) and retracted position (seeing Figure 12) mobile actuating be with 86 and described 54.
By illustrating how be with 86 can be at extended position when pelvic support member 126 activates when retracted position (seeing Figure 11), with activate when pelvic support member 126 how be with 86 can be at retracted position when extended position (seeing Figure 12), the independently operability of equipment 230 is illustrated in Figure 11 and Figure 12.Certainly, user can select the independently location combination of expectation of described 54 and pelvic support member 126 to obtain the support of the most comfortable.Although not shown, also understand lumbar support assemblies 50 can comprise extra functional with vertically in the interior adjusting lumbar support of back of seat 14 to hold different users.For example, whole driven unit 74 can move so that bending actuating can be regulated vertically according to demand with 86 summit in back of seat 14 vertically along bar member 42O.In addition, do not departing from situation of the present invention, other lumbar support assemblies can substitute graphic assembly 50 (for example seeing Figure 15 and Figure 16).
Equipment 230 also comprises the seat selection of optional fan/hair-dryer 70 for heating or freeze.Hair-dryer 70 is illustrated and is arranged on plate 250, and this plate 250 is supported between transverse member 48 or with transverse member 48 and forms, but hair-dryer 70 also can connect with equipment 230 in alternative mode.Can be by the air guiding from hair-dryer 70 through the hole 66 (seeing Fig. 5) in described 54 to allow air to pass described front portion that flow to back of seat 14.
